History and Facilities

Our History

From its roots as a modest homestead in the late 1780s, the Evergreen Heritage Center expanded into a plantation in the 1820s and evolved into a Victorian homestead in 1870s when Winfield Scott Trimble planted 13 varieties of evergreen trees and named the property Evergreen.

Evergreen is recognized by the Maryland Historical Trust (1976) and listed on the National Register of Historic Place (2015). Visitors may, by appointment, tour the Evergreen Mansion (now a museum) and Evergreen Barn with its original stone foundation, hand-hewn chestnut beams, and plantation-era farming implements. Visitors may hike the Evergreen Coal Trail, which was used to haul coal deep-mined on the property in the early 1900s.

    Outdoor Learning Stations. The EHC offers a dozen outdoor learning stations and accompanying lessons that explore forest ecology, soil and water conservation, climate change, and alternative energy solutions. Station lessons, which are available in versions for elementary, middle, and high school students, align with the Maryland State Curriculum and Environmental Literacy Standards and contain classroom and schoolyard components accessible by educators online.

  • Heritage Hoop House. This 2100-square foot hoop house (high tunnel greenhouse) demonstrates best practices in sustainable agriculture including rainwater collection for irrigation and solar energy generation for power. This structure supports programs to replace invasive species with native plants and trees, regenerate heritage tree/plant species, and establish pollinator and wildlife habitats.

  • Heritage Sawmill and Wood Shop.  This companion to the Heritage Hoop House supports experiential learning/training in sustainable forestry practices that strive to maintain forest health, biodiversity, and capacity for regeneration while also meeting increasing demand for forest products.

  • Energy Learning Station. This 200-square foot facility enables students to explore energy science and technology and to evaluate renewable and other energy-saving solutions.

  • Evergreen Pond. With its hand-crafted wooden dock, our large pond is the perfect resource for outdoor science activities and exploration.
